Problem Summery: One of the BBS developers asked a question about setting the background-color of separate header of DataGrid component. At first, I guessed that the style headerColors of DataGrid would help us. However, this style controls all headers’ background-color. Does headerStyleName of DataGridColumn would help us? Unfortunately, the answer was no. Setting the “background-color” of the style “myDataGridColumnStyle” which I assigned to “headerStyleName” took no effect. No resolution? I googled a lot, found no existing resolution.
